About this product

Model:  stellalyra_8_f6_dob
Part Number:  GS680-D

The UK's BEST 8" Dobsonian telescope! 

Designed and manufactured to a very high standard by Guan Sheng Optical (GSO) in Taiwan. 

With an 8" aperture, this easy-to-use Dobsonian telescope is an excellent choice for visual astronomy.

Viewing the lunar surface will feel like you can reach out and scratch plaster! Venus and its phases are also viewable. In good seeing conditions, you can observe Mars with surface shading and polar cap, Jupiter's weather bands and a number of its Moons and Saturn with its rings, including the Cassini division, are also clearly visible. So too, are many deep sky objects such as galaxies and nebulae. For many owners, this telescope will provide a lifetime of observing. 

All StellaLyra Dobsonian telescopes are fitted with a quality GSO aluminised parabolic primary mirror with a minimum 93% reflectivity and a silicon-dioxide protective overcoat to ensure the surface remains bright for years to come.  

Collimation knobs on the primary mirror cell provide easy collimation adjustment without tools, and an integrated fan provides fast cooling. 

This 8” model also features an impressive CNC-machined 2" Crayford focuser with 1:10 dual-speed focus adjustment for smooth, precise focusing. And no image-shift!

The focuser includes a 2" to 1.25" adapter, so you use both 2" and 1.25" eyepieces and accessories. Brass compression rings grip them securely without marring their nosepiece. A convenient 35mm focus extender is also supplied so you can achieve focus easily when using most long focal length 2" eyepieces. 

Two fully multicoated eyepieces (1.25" 9mm Plössl & 2" 30mm SuperView) are included so views will be clear and sharp from the outset.  

The Dobsonian base is delivered flat-packed and is easy to assemble. 

A robust roller-bearing assembly provides smooth, reliable azimuth adjustments. Metal plates above and below the bearings prevent them from sinking into the softer wood (no divots!), so the movement remains smooth, even after years of use. 

For altitude adjustment, a robust steel shaft and CNC-machined metal plates with large knurled tension adjustment knobs, one on each side, provide smooth, precise movements and adjustable tension. 

The mount also features a convenient balance adjustment mechanism with an engraved scale that enables the telescope to be moved forward or backward for precise balance. This is useful when changing from a small eyepiece to a large, heavy one or when adding a second finderscope or binoviewer. 

For comfort and convenience, a Right-Angled Correct Image 8x50 finder scope is included, so no cricked neck!  

NOTE: The assembly instructions are generic for 8", 10" & 12" models, so please don't be concerned if your telescope is supplied with fewer screws than shown in the instructions. You will have the correct number.

Great value first scope
15 February 2024  | 

Got this scope in early December. About a month wait from first ordering but the predicted availability listed by FLO was spot on. Arrived very well packaged and grouped with other purchases so didnt need to co-ordinate for several deliveries. FLO were first rate when I changed my order during the waiting time.

The scope itself is made with quality materials and feels like it will last a lifetime. 30mm EP, finder scope and focuser are all decent and wont need upgrading.

Been frustratingly cloudy since receipt but have used a few times now. Set up is rock solid and easy to manoeuvre. Even from light polluted garden in SE London had great views eg cloud bands on Jupiter.

Im very happy with this purchase. An excellent first scope for stargazing and first rate company to buy from.

First proper scope
25 January 2024  | 

Im new to astronomy and originally had a 102mm refractor. But after struggling with an unstable mount and a lot of aberration, I looked into a different scope and all things pointed to an 8 Dob. I cant tell you how pleased I am with it. The Stellalyra is extremely well made and the 30mm eyepiece is a very good quality. I bought a 12mm and Barlow to accompany it and straps to carry the scope. I find it easy to move around and collimating and aligning the scope were very straightforward for a newbie. The views are just fantastic. I can clearly see the moons craters in detail and Jupiters gas clouds and moons are extremely clear. Saturn just looks beautiful. Im in the early stages of looking at deep sky objects and need to learn the constellations better before I venture a bit further afield. But so far, Im really happy with the scope and cant wait to get out when the sky is clear. First light optics were fantastic. Ordered midday and arrived by 10am the next and their customer service was great. Chris was extremely helpful when I was asking advice on eyepieces.
Theyre definitely my go to on any equipment and advice I need as I get further into my new hobby.

SellaLyra 8" Dobsonian
09 December 2023  | 

Long wait due to supply issues but well worth the wait. Put together on the day it arrived and wow had a clear night! Was expecting to have to collimate the scope but it was fine out of the box! I live in a light polluted city but Jupiter, belts and moons, pleiades and andromeda looked awesome. Only one slight niggle. When tightening the base the small metal tube stands proud ( slightly too long ) So couldn't adjust the tension on the central bolt and small bearing. I could have cut it down but it was easily remedied with a spacer. Looking forward to heading out to dark sites with the local club now. Thanks FLO.

A wonderful telescope, thoughtfully-designed and well-built
21 May 2023  | 

I have owned this telescope for many years (under the Revelation brand). The optics are wonderful and - of great importance - the platform is extremely stable, offering vibration-free views under conditions that most other telescopes can find challenging. The focusser is very precise and free from excess play. The altitude pivot mechanism is of particular note, with large-sized tension knobs that provide fine control over the desired stiffness of movement. Once balanced for your accessories, the mechanism (contrary to what is implied in the description) never needs touching again, as there remains enough stiffness in the mechanism to cope with a wide range of eyepieces and other attachments.

The fan is quiet and unobtrusive, and the built-in eyepiece rack surprisingly handy. Overally, it is always a pleasure to use this telescope.

It is worth noting however, that an 8" Dobsonian like this is at the limit of what most people can comfortably carry. It's heavy - there's no denying that, and if transporting by car to an observing site, then I would recommend you either buy a big cloth bag for the tube, or alternatively fashion a carry shoulder carry strap out of luggage straps (the pivot mechanism can be used to prevent such straps from slipping). In this way, you can carry the tube under one arm, and carry the base (which has it's own handle) with the other hand. In any case, be aware that you'll have to stop for a rest break or two on anything but the shortest of walks.

The quality of stability the views however, make it all worthwhile.

Note also that the height of the base, and the 8" form-factor allows a simple lightweight walking chair to be used. Nothing more sophisticated is required provided that you operate the scope by sitting alongside it rather than square-on. With such a set-up, I have never found the need for an adjustable astronomy chair, and bending forwards for low altitudes, and then sitting up straight for high altitudes feel entirely intuitive, natural and comfortable.

If this size of scope suits you, then I wholeheartedly recommended this model.

StellaLyra 8" f/6 Dobsonian
08 May 2023  | 

This is my first large aperture scope and I must say I'm impressed with the construction and robustness of the design. The law that says as soon as you buy a new scope you don't get a clear night to see its capabilities is working overtime in my case but I did manage to view the moon for over an hour on one occasion and I was very pleased with the sharpness and definition of the image. The delivery and packaging from FLO was exceptional, the scope arrived within 24hours of ordering. I am very pleased with my purchase.

Fantastic service
14 March 2023  | 

Ordered the scope on the Saturday afternoon and it arrived Tuesday lunchtime. Regular updates from DPD and arrived exactly when they predicted. Packaging was excellent, all items were well protected and arrived in perfect condition. Assembly was straight forward and instructions on the website were fine.

The scope itself and accessories are of a high standard. I also purchased the SL 2x Barlow. Really pleased with the quality of these items. I even managed a few hours viewing after the snow cleared up.

All round exceptional service. Highly recommend the scope and First Light Optics. I will definitely be purchasing from them again in the future.

StellaLyra 8" Dobsonian telescope.
11 March 2023  | 

After reading so many good reviews about FLO, I decide to buy from here.
Couldn't be happier with the purchase and delivery was exactly as expected.
So many astronomers recommended an 8 inch Dob for the best compromise of size, weight, portability, ease of use and performance.
This scope has great features that make it a pleasure to use.
Right angled finder scope, lazy Susan base bearing, adjustable optical tube balance position, super quiet fan for primary mirror, Black tube and base.
I did wonder if the base bearing should be greased but an internet search was in favour of leaving it ungreased for best feel. It shouldn't need grease anyway as it's never rotated at speed but wanted to do the right thing.
Only used for one night at time of review but was delighted at the quality of the telescope and views through the eyepieces.
Bottom line, very happy and will be back when I'm ready to buy accessories.

Near perfect setup
25 February 2023  | 

Firstly, the service from FLO was good. Quick despatch and I usually find DPD to be decent. I helped the driver with the OTA box which is awkward and heavy for a single person lift.

The construction is simple but there are no instructions supplied so check the video online called Zhumell Deluxe Dobsonian Reflector Telescope Video which is basically the same thing. Take your time because it is easy to bolt together some bits the wrong way round.

Collimation was slightly out as you might expect from the delivery process. I used a collimation cap (6 from FLO) and the process was simple enough and can be done while the inevitable cloud cover hangs around.

The supplied accessories are what sets this apart from competitors. I found the finderscope very easy to use, the eyepieces are decent for beginners. I like the dob mount with the ball bearing style rotation. With the balance roughly right we had no problems nudging the telescope smoothly to follow the targets. The focuser feels like a quality instrument and despite needing the supplied extension tube for the 2 eyepiece we have found focus easily on most targets.

Our first night out was not the best seeing but we used the low power eyepiece to view the Orion Nebula which was very clearly visible. We used a bst starguider 5mm EP (not supplied) to view jupiter through some wobbly atmosphere and we saw it with its moons. The equatorial bands were just about there too. On a better night Im confident we see much better detail.

Do consider the size and weight of this telescope. I can lift the whole thing and walk around with it but I would prefer to use a dolly board or sack barrow arrangement to save my back. Storage is potentially an issue too.

Overall I am very pleased. This was a present for my 14 yo daughter who has spent 5 years battling with a junk telescope (76/700) complete with plastic eyepieces and wobbly tripod. Somehow her enthusiasm never wavered and we just had to reward her with a decent setup. Im glad we chose this.

Stellalyra 8" Dobsonian
20 February 2023  | 

Very pleased with my recent purchase , it's my second scope which took a lot of research before deciding on this Dobsonian for visual astronomy . I've not had the chance to use it much so far but have had decent views of Jupiter , Orion's nebula and M35 using the standard lenses supplied . It's a well made telescope with excellent standard equipment its taking a little to get use to it after years of using a refractor and eq mount but wanted something easier to use as I'm also teaching my 9 year old and so far he's doing pretty well . Delivery and packaging was perfect ( was considering going to pick up as was worried how it would be treated but arrived in perfect condition ) I highly recommend this scope and firstlight optics and will be using them for further purchases in the future
